RUBIACEjE. 345 



Of the other Swartzian Psychotria, three belong to Palicourea, and P. citrifolia is Rudgea 

 caribaa ; several West Indian species of authors are unknown to me, and their description 

 too incomplete to be recognized : viz. P. laxa and involucrata, Sw., both neither found in 

 his own nor in the Banksiau collections ; P. Balbisiana, DC, and P. congesta, Spreng. : all 

 these came from Jamaica.
